Why watermarking exists elsewhere
Watermarks and 'free tier' stamps are conversion devices: they make the free output embarrassing enough that professionals pay. They exist because those generators run servers (dynamic codes) with real per-user costs. A browser-based static generator has no such costs, so there's no economic reason to mark your work — and none is applied.
What clean output means in practice
The SVG opens in design software with no extra layers to delete. The PNG has no border text to crop. The PDF is a finished page, not an advert. If you add your own logo to the centre, that's your brand on your code — the only mark present.
Attribution isn't required either. If you'd like to credit the tool, we're grateful, but nothing in the output or terms asks for it.
Verifying any generator's output
Worth doing wherever you generate codes: decode the downloaded file (our scanner does it in-browser) and confirm the content is exactly your URL — not a redirect through the generator's domain. Some services embed their branding invisibly, by routing scans through themselves. Static codes made here decode to precisely what you typed.
Mistakes to avoid
- Check the centre of codes from other tools — some embed a logo you didn't ask for.
- Decode downloads to catch hidden redirects (a watermark you can't see).
- Cropping a watermark off a raster file usually damages the quiet zone; regenerate cleanly instead.
Common questions
Can I use these codes commercially?
Yes — on products, packaging and advertising, with no licence or attribution needed.
Is the SVG watermark-free too?
Yes — one clean vector path, no branding layers.
Why is it free with no watermark?
Static codes cost nothing to serve; the watermark model exists to upsell dynamic-code subscriptions, which we don't have.
Can I add my own logo?
Yes — upload it in the generator and error correction is raised automatically so the code still scans.
